MDKSA-2003:082

Problem description

A vulnerability was discovered in the transparent session ID support
in PHP4 prior to version 4.3.2. It did not properly escape user-
supplied input prior to inserting it in the generated web page. This
could be exploited by an attacker to execute embedded scripts within
the context of the generated HTML (CAN-2003-0442).
As well, two vulnerabilities had not been patched in the PHP packages
included with Mandrake Linux 8.2: The mail() function did not filter
ASCII control filters from its arguments, which could allow an attacker
to modify the mail message content (CAN-2002-0986). Another
vulnerability in the mail() function would allow a remote attacker to
bypass safe mode restrictions and modify the command line arguments
passed to the MTA in the fifth argument (CAN-2002-0985).
All users are encouraged to upgrade to these patched packages.
